The Australian Northern Prawn fishery (NPF) is one of the few that has adopted a dynamic version of a ‘maximum economic yield’ (MEY) target, and, on this basis, the fishery is undergoing a process of substantial stock rebuilding. This paper details the bioeconomic model that is used to...

The Carbon Farming Initiative (CFI) and other carbon trading programs have been promoted as alternative sources of income for agricultural producers, particularly those on marginal land. This paper presents the results of a bioeconomic model developed to compare the relative returns from a beef...

A bioeconomic model of reservoir aquaculture in northern Vietnam, called BRAVO, is presented. The biological model is based on a conventional von Bertalanffy growth function and the economic model is a net revenue function. The greatest source of costs for the operation are restocking costs (75...

Economic evaluations of the benefits of integrated weed management often only consider the benefits of management in the crop phase, and ignore the impact of rotational options. In particular, non-crop phases such as annual and perennial pasture phases can have a substantial impact upon weed...

The decline in extent of wild pollinators in recent years has been partly associated with changing farm practices and in particular with increase of pesticide use. In this paper we combine ecological modelling with economic analysis of a single farm output under the assumption that both...

This thesis consists of four papers studying economic aspects of natural resource and environmental management in Namibia. <p> Paper [I] analyses changes in Namibian energy use patterns between 1980 and 1998. The study finds that, unlike their counterparts in many other developing countries where...</p>

Where a fish stock straddles or migrates between country A's exclusive economic zone (EEZ) and country B's EEZ, or the high seas, vesting ownership rights in the stock with A does not ensure efficient harvesting of the stock. This problem arises in the case of migratory tuna stocks in the...

This study extends an original bioeconomic model of optimal duck harvest and wetland retention by bringing in amenity values related to the nonmarket (in situ) benefits of waterfowl plsi the ecosystem values of wetlands themselves. The model maximizes benefits to hunters as well as the amenity...
